## How to find the domain and range of a piecewise function | Functions | Algebra I | Khan Academy

So we have a piecewise linear function right over here for different intervals of x. g of x is defined by a a line or the line changes depending what interval of x we’re actually in. And so let’s think about its domain, and then we’ll think about its range. So the domain of this,…

– [Voiceover] Let’s say that f of x is equal to x plus 7 to the third power, minus one. And let’s say that g of x g of x is equal to the cube root of x plus one the cube root of x plus one, minus seven. Now, what I wanna do now…

## Intervals and interval notation | Functions | Algebra I | Khan Academy

– [Voiceover] What I hope to do in this video is get familiar with the notion of an interval, and also think about ways that we can show an interval, or interval notation. Right over here I have a number line. Let’s say I wanted to talk about the interval on the number line that…

– [Instructor] Consider the following piecewise function and we say f(t) is equal to and they tell us what it’s equal to based on what t is, so if t is less than or equal to -10, we use this case. If t is between -10 and -2, we use this case. And if t…
